haw-e PUMP.

Application filed December 16, 1913.

To 022 107mm it may concern Be it known that I, HIRAM W. PIERSON, a citizen of the United States, residing at Evant, in the county of Hamilton, State of T exas. have invented certain new and useful Improvements in Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in pumps, and particularly to windmill pumps.

The principal object of the invention is to provide a simple hand attachment for oper ating the pump plunger independently of the windmill rod.

Other objects and advantages will be apparent from the following description, when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is a side elevation of my device. Fig. 2 is a rear elevation. Fig. 3 is a top plan view, the pump rod being in section. Fig. 4 is a sectional detail of the member which connects the pump rod with the windmill rod. Fig. 5 is a ver tical section on the line 5-5 of Fig. 1. Fig. 6 is a vertical transverse sectional view on the line GG of Fig. 3.

Referring particularly to the accompanying drawings, 10 represents the upper end 0'! the stand pipe which projects above the well, this pipe being provided with a discharge nozzle or spout 11. \Vithin this pipe is the pump rod 12 which carries the usual plunger heads or pistons, not shown. Secured to the side of the pipe, near the upper end is an outstanding bracket 13, this bracket being secured to the pipe by means of the clamps 14 and 15. These clamps permit of the ready attachment or removal of the brackets, so that the same can be attached to the stand pipe of any well. Secured to the bracket, and extending vertically thereabove, and in parallel relation, are th uprights 16, the inner end of an operating lever 17 being pivotally mounted between the upper ends thereof. The inner end of the lever 17 projects beyond the opposite side of the uprights, and carries a. weight 18 for holding Specification of Letters Patent.

the lever normally in horizontal elevated position. Also pivoted between the upper ends of the uprights, and above the lever 17 is a link 19, the opposite end of which is pivotally connected to the pump rod 12 above the stand pipe.

Secured to the bottom of the windmill rod 20 is an L-shaped casting 21, the horizontal portion of which is formed with a vertically disposed aperture 22 through which is disposed the upper end of the pump rod 12. The upper end of the rod has an enlarged head 23 which prevents the rod from sliding all the way through the opening, the lower end of the rod being coupled to a lower sec tion 24 by means of a coupling 25. It will of course be understood that this section 12 is inserted through the opening 22 from above.

The outer end of the lever 17 has attached thereto a depending cord 26 to the lower end of which is secured a hand grip 27. The inner projecting weighted end of the lever 17 engages the underside of the link 19 between its points of attachment with the uprights and the pump rod, and when the lever 17 is pulled downwardly, by means of the cord 26 the weighted end will rock the link 19 on its pivotal connection with the uprights and raise the plunger or pump rod so that it slides freely through the opening 22. The weight of the pump rod sections are sufficient to cause them to fall by gravity, it being only necessary to raise the pump plunger in the operation of the pump. lVhen the pump is operated with the windmill, the rod 20 is lifted by the engagement of the head 23 with the horizontal portion of the member 20.

From the foregoing, it will readily be seen that I have provided a simple device which is comparatively cheap to manufacture, and which may bequickly and easily attached to the ordinary stand pipe of a well.

lVhat is claimed is:

A hand operating device for a windmill pump, a bracket detachably secured to the pump stock. parallel uprights carried by the bracket. a link pivotally connected at its opposite ends respectively to the pump rod and the uprights, a slidable connection between In testimony whereof I atiix my signature the pump rod and the wmdnnll rod, and an 1n the presence of two witnesses.

operating lever provided with a weight in HYRAM I PTERQOY one end and pivotally mounted between the L l 5 uprights in such position that the Weighted Witnesses:

end is disposed in engagement With the S. A. PERSON,

underside of the said link. L. D. PIERSON.
